How to Find Out the Firmware Version in Linux

The firmware version can be easily checked out in Linux by dmidecode, a tool to locate the computer’s Desktop Management Interface (DMI) table and dump the content to human-readable content. The dmidecode can find out more information, but we only used to find out the firmware version here.

One command simply:

# dmidecode -s bios-version

The BIOS version will be printed out. That’s it!

If the command is not available, you need to install it first. On Fedora Linux, you can use ‘yum’ to install it as follows.

# yum install dmidecode

One example of the output is as follows.

# dmidecode -s bios-version
